Ok I've got a 88 GTU that's getting ready for a turbo conversion and my goal is to run about 15 psi boost when it's finished. I was thinking about using a water injection setup to reduce the risk of detonation. I would run a front mount intercooler also, so at what point in the intake stream would I need to install an injector? Have you guys had any experience with water injection? If you have, let me know of any pros and cons, and how basically to set it up.

 

15psi on stock turbo's? Way to go, me too! Frontmount, e6k 550/1600cc injectors, do us a favor and don't run 15psi. Turbo can barely handle it and going from n/a to 15psi turbo is a scary thing indeed! Water injection is really only needed above 15psi.

 

the stock turbo will have a hard time making 15psi

i'm planning on running a series 5 turbo and manifold, i've heard those do farely well at 15 psi
